Question

我有基于SBT的Scala库，我将其发布到Maven存储库：

organization := "com.mycompany"
name := "mylib"
version := "0.0.1"
scalaVersion := "2.10.6"
crossScalaVersions := Seq("2.10.6", "2.11.7")
scalacOptions ++= Seq("-feature", "-unchecked", "-deprecation")

libraryDependencies ++= Seq(
  "org.scalaj" %% "scalaj-http" % "2.2.0",
  "org.json4s" %% "json4s-jackson" % "3.3.0",
  "org.slf4j" % "slf4j-api" % "1.7.13",
  "org.slf4j" % "slf4j-simple" % "1.7.13"
)

isSnapshot := true
publishMavenStyle := true
publishTo := {
  Some(s3resolver.value("My Repo", s3("mybucket")).withMavenPatterns)
}

我将这个库包含在另一个项目中：

libraryDependencies ++= Seq(
  "com.mycompany" %% "mylib" % "0.0.1"
)

正在运行sbt sbt-dependency dependencyTree只会显示：

[info] Done updating.
[info] default:another-project_2.10:1.2 [S]
[info]   +-com.mycompany:mylib_2.10:0.0.1
[info]

我无法看到所有第三方依赖项：org.scalaj，org.json4s等。

编辑：此外，在构建程序集时，uberjar也缺少这些依赖项。

部署到Maven存储库的.pom文件确实包含所有提到的依赖项，而~/.ivy2/cache/com.mycompany/mylib_2.10/ivy-0.0.1.xml则没有。

在mylib /中运行sbt about：显示：

我做错了什么？

Answer 1

您的build.sbt文件包含

行

publishMavenStyle := true

根据the documentation

一个POM由makePom动作生成并发布到存储库而不是常春藤文件

我可以假设ivy.xml刚刚没有生成，而你看到的那个是前一次运行的残留，当publishMavenStyle尚未设置时。

由于您的工件已发布到Maven存储库中，您是否尝试从~/.ivy2/cache/com.mycompany/mylib_2.10中删除该工件并检查依赖关系树列表的结果？

为什么没有检测到传递依赖？
